7.10.12 The ndbinfo cpustat_50ms Table

The cpustat_50ms table provides raw, per-thread CPU data obtained each 50 milliseconds for each thread running in the NDB kernel.

Like cpustat_1sec and cpustat_20sec, this table shows 20 measurement sets per thread, each referencing a period of the named duration. Thus, cpsustat_50ms provides 1 second of history.

The following table provides information about the columns in the cpustat_50ms table. For each column, the table shows the name, data type, and a brief description. Additional information can be found in the notes following the table.
